Questions and Answers

Does it really work, I know most 'mains surge protection' adverts are a scam and do nothing ?

Yes, these really do work as they only have to protect your Ethernet signals inside your shielded CAT5e cable.

Nearby lightning is that really a problem ?

You bet. I once had a single lightning bolt hit about 1km away, and it blew two network ports on two network switches in my home LAN. I had a 20 metre UTP cable running inside between the two network switches.

But my CAT5 cabling is indoors, it's protected right ?

Wrong! it's the EMP (Electro Magnetic Pulse) from nearby lightning that does the damage, and it gets inside your house as easily as the signal for your TV or radio.

What is the best protection I can get ?

Two kits per Access Point, one near the Access Point up the mast, and one at the lowest point outside the house, grounded to a copper grounding stake

What is the next best protection I can get ?

One kit up the mast, protecting the Access Point. This is the most common deployment.
